Calm Before the Storm is a song that makes its debut in the eleventh Dark Parables game, The Swan Princess and the Dire Tree (not to be confused with the Purple Tide version, which can be found here, or the Tinderbox version, which can be found here).

The Swan Princess and the Dire Tree Edit
In this game, the song is used as background music for puzzles and FROG scenes. Its title is most likely a reference to the calm before Elise killed Flora.
